SPRAY-NOZZLE."

To all 'wlwm z't my concern: A Be it known thatI EUGENE ROBERTS, citie zen of the Unitedv tates, and resident of Salt Lake City,'county of Salt Lake, State of Utah, have invented certain new: and use-' so that, each portion of the walled. up body of sugar shall receive neither too. littleinor too much of the liquid spray directe'dagainst dissolving and waste of sugar, while a deficiency of spray at any point resultsin an incomplete or inefficient washing. The 'requirements of different grades of sugar and different volumes of sugarto be washed according to the size of the centrifugal basket employed, make it desirable to secure a convenient and accurate adjustment of the volume and shape of the spray to suit individual conditions,

; lt is thelobject of the presentjinvention to provide a spray nozzle constructed andarr' ranged to make it possible 'and-convenient-to secure a wide range of adjustment and con: trol of the spray suited to these varyingconditions. To this endthe invention comprises, generally speaking, a segmentalchamberor nozzle, having an outer peripheralfwall, curved about a transverse or substantlally horizontal axis, and provided with-a series of close perforations, combined witha cut off plate closely fitting the interior orconcave face-ofthe peripheral wall or spray plate,

and a'transverse adjusting screw for adjustingsaid plate acrossthe perforated area, so

as to cut off a greater orless number of the spray orifices, in order'to narrow or widen the fan shaped spray. The cuttln-g-offof the adjustable plate maybe given anytde sirable contour in order to vary the amount of spray delivered at dilferent heights on the sugar wall, and the-connection of said plate with theremainder of the nozzle is suchas .Specificationof Letters Patent. Patented'sept, Application filed September 29, 1917; Serial No. 193,879.

va peripheral wall 6 similarly curved, and

whose interiorgportion or area is provided so that plates of various contours maybe used as desired; These and other features of the invention will be particularly de-v scribed in this specification, and will be de-. fined in the claims annexed hereto. In the accompanying drawings '1 have illustrated aconvenient. and particular form of spray nozzle illustrating the principles of this invention in which i .7

Figure l is a front'elevationof the nozzle, showingthe exterior face of the perforated plate or spray plate.

to permit its ready removal and replacement i Fig. 2isa side elevation of the device,the

A lower half being shown in, the central section.i Fig. 3 is a horizontal section through the central part ofthe spray nozzle. g y Fig. 4 ;is a' detailview showing in perspective the cut off member or,plateby which the volume of the spray is regulated.

In the practice of. my invention according to the-form illustrated in, the drawings,-?I

employ an approximately segmental casing a,-the outer faces-of whose side and top and bottom walls are convexly curved about a transverse axis, which axis is substantially horizontal when the device is in use. I The chamber or nozzle a is provided with comprising an oblong concavo-convex plate,

with a series of-numerous, closely arranged, perforations which radiate or. diverge in vertical'planes to,.throw a fan shaped spray.

To prevent leakage I prefer to interpose betwejenthe outer' edge's of the nozzle casing andtheinside convex face of the spray plate b, a packing 0. 7 1 a The spray plate I) is removably secured to thenozzle-member-by a series ofscrews d normally set down to squeeze the interposed packing to prevent leakage} l A 1 At the middle of thesidewalls ofthe nozzle'are provided opp'osedapertures, intends 'ed tolreceifve the adj Listing screw efand form abearing therefor to hold said screw inop erative position. A cut off plate f shown inFig. 4,,is formed with its outward con vex face, curved to snugly fit againstthe in-' side of the convex'face of the spray plate or member I). It will be noticed that one edge of said spray plateis formed with: a "series of-steps ornotches as at f f and f which indent :the plate laterally or transversely,

These indentations are employed for the purpose of permitting a relatively greater volume of liquid toibe delivered at those points rather than at the widest portion of the plate, and the volume and extent ofthe indentations will correspondto the requirements imposed by particular conditions, both as to the nature and grade of the sugar being treated, as well as to :the size and,

thickness of the sugar wall built up particular basketemployed. V

The cut off member is provided with rearwardly extending notched flanges 7 an F, the notches being located to permit the respective flanges to straddle the adjusting screw when in position. An elongated nut g is mounted on the adjusting screw 6* and is shaped to fit in between the flanges f and f with its outer portion in" front of the screw, extending vertically between the two in the flanges close to the inside face'of the; plate 7 described.

Y 7 so that the nut is prevented from rotating with the screw, and is therefore; forced to travel alongthe screw, as the screw is 1'0 tated, in order-to shift the cut offmember transversely over the perforated area of the spray plate- 'By this movement, agreater or less number of perforations are closed or cut off, and thus the width of the spray from side to side'is narrowed or widened. V

In order to prevent leakage jbetween the cut off member and the perforated spray plate, I provide two set-screws h which are tapped into the wall of the spray nozzle im' mediately behind the end portions of the cut eff-plate, so-as to set the cutoff plate snugly against the inside face of the spray plate. These set-screws also serve to lock thecu-t off plate or member against any accidental movement from position.

As a further precaution "against leakage between the cutofliplate and the spray plate,

I employ athin sheet of packing 0 which is preferably cemented or otherwise secured to.

the fconvex face of the'cut off plate f.

VVha't I claim is: I
